Ultrasonic cleaning machine is widely used in railroads, automobiles, aerospace, aviation, machinery, electronics, liquid crystal (LCD) manufacturing, optics, medical, electroplating, coating and vacuum coating pretreatment and other industries. These so-called ultrasonic cleaning machine power is also usually refers to the ultrasonic output power of the cleaning machine, usually the greater the ultrasonic output power, the stronger the cleaning strength, the efficiency will be a little higher. In the procurement of ultrasonic cleaning machine, not only need to look at the capacity and frequency of the cleaning machine, but also take into account the size of the ultrasonic power. Ultrasonic cleaning machine cleaning effect is not good mostly because did not choose to the right power.
First, the power is not the higher the better, the most important thing is appropriate
Ultrasonic cleaning machine output power, the higher the acoustic output power, the stronger the cavitation intensity, although beneficial to the cleaning effect, but for the bottom of the tank cavitation corrosion will be more serious, which leads to shorten the service life of the cleaning machine; but if the ultrasonic cleaning power to pick the small words, often jeopardize the cleaning time. Item cleaning time, resulting in items cleaning time is long or cleaning effect error.
Second, ultrasonic cleaning machine power - how to choose the frequency of ultrasonic cleaning machine
The ultrasonic cavitation threshold and ultrasonic frequency has an inseparable relationship. The higher the frequency, the higher the cavitation threshold. The lower the frequency, the smaller the cavitation threshold will be, the easier it will be to produce the cavitation effect, and in the case of low frequency, the liquid is compressed, dilute the effectiveness of the longer interval, so that bubbles can grow to a larger size, enhance the cavitation strength, conducive to ultrasonic cleaning effect. Therefore, low-frequency ultrasonic cleaning machine is more suitable for large parts or stains and cleaning the surface of the workpiece adhesion is relatively high, such as automobile engines, valves and so on. But low-frequency ultrasonic cleaning machine is easy to corrode the surface of the cleaning parts, its frequency is relatively low, the noise generated is relatively very large. Therefore, for the surface of the workpiece requires a high degree of hardness of the parts should not be selected relatively low frequency.
Relatively high-frequency ultrasonic cleaner penetration is relatively strong, in the same sound intensity, are more than the number of low-frequency cavitation bubbles, so more suitable for cleaning relatively more precise, more complex surface structure, blind holes in more parts. And high-frequency ultrasonic cleaner noise is relatively small, but the cavitation strength is relatively low, more suitable for some precision parts, cleaning stains and cleaning the surface of the workpiece adhesion is relatively poor.
Third, ultrasonic cleaning machine power formula
(1) according to the transducer (commonly known as vibration head) to calculate. Currently on the market commonly used transducer power there are two main: 50W/PCS, 60W/PCS.
(2) know the length and width of the tank on the line. Every 100mm a vibrator, horizontal and vertical are this distance, the vibrator power is usually used 50W or 60W. 600 * 400 = 240,000 divided by 10,000 = 24 vibrators 24 * 50 = 1200W24 * 60 = 1440W.
(3) Slot is usually placed in the bottom of the 600 * 400mm surface, usually equalized rows of The 24 vibrators on the line, if the pollution is heavy, should be appropriate to increase the power, equalize the placement of 28, if the 50W vibrator, the total power of about 1400w, matching a 1500w generator on the line.
(4) If the vibrator to the next, ultrasonic cleaner specific power calculation is 60 * 40 * 0.55 = 1320W.
Ultrasonic cleaner power selection of ultrasonic cleaning machine cleaning effect and cleaning time is a very important determining factor, only scientific and reasonable selection of suitable for their own ultrasonic power, the formation of the cleaning effect is more Suitable.
